What is this? I’ve never seen one before and it’s in my house!
It’s about an inch and a half. The narrow depth of field in my camera requires that I show you the crazy antenna things and apparent eyes in two different pictures.

Male Green Lynx Spider

Greetings from the other side of the 110 freeway Martha,
Our offices are in Mt Washington, Los Angeles, CA, and though you did not provide a state, we are guessing you might be our neighbor.  This stunning spider is a male Green Lynx spider,
Peucetia viridans.  Green Lynxes do not snare their prey with a web.  They hunt and pounce on insects and other arthropods.  They seem to have a fondness for awaiting on blossoms for pollinating insects and they often gravitate to rose bushes.  A female will eventually mature and once she has mated, lay one or more egg sacs that she fiercely guards.  Green Lynx Spiders are perfectly harmless to humans.  We have taken the liberty of combining the sharp focus components of your individual images so that both the eyes and pedipalps are sharp.  Male spiders have more developed pedipalps than females and they are used during mating.  According to Encyclopedia Britannica online:  “Spiders have six pairs of appendages. The first pair, called the chelicerae, constitute the jaws. Each chelicera ends in a fang containing the opening of a poison gland. The chelicerae move forward and down in the tarantula-like spiders but sideways and together in the rest. The venom ducts pass through the chelicerae, which sometimes also contain the venom glands. The second pair of appendages, the pedipalps, are modified in the males of all adult spiders to carry sperm (see below the section Reproduction and life cycle). In females and immature males, the leglike pedipalps are used to handle food and also function as sense organs. The pedipalpal segment (coxa) attached to the cephalothorax usually is modified to form a structure (endite) that is used in feeding.”  The additional explanation continues:  ” In male spiders the second pair of appendages (pedipalps) are each modified to form a complex structure for both holding sperm and serving as the copulatory organs. When the time for mating approaches, the male constructs a special web called the sperm web. The silk for it comes from two sources, the spinnerets at the end of the abdomen and the spigots of the epigastric silk glands located between the book lungs. A drop of fluid containing sperm is deposited onto the sperm web through an opening (gonopore) located on the underside of the abdomen. The male draws the sperm into his pedipalps in a process known as sperm induction. This may take anywhere from a few minutes to several hours. Sperm induction may occur before a male seeks a mate or after the mate has been located. If more than one mating occurs, the male must refill the pedipalps between copulations. ”

Thank you so much, Daniel! This is way beyond my wildest hopes. Absolutely fascinating!
And yes, we are neighbors across the Arroyo. I forget that you have an international following and I should have been a little more complete.
I will not hesitate to send you photos of all my mystery insects. I have some powerful macro lenses and love to get a good photo. In this case, I didn’t even set up my tripod. Next time! Thanks for compositing the detail shots.
What a thrill!
Martha

If we can use our PhotoShop skills to improve the anatomical renderings of our favorite local species of spider, then we will have to overlook the blatant disregard for journalistic journalistic integrity it connotes.  Our biggest defense is that when it was conceived, this website was an art project.  It has really metamorphosed from that remote time in another millennium.

I found this unique (or maybe not, but I’ve not encountered it before) specimen of arachnid on one of the hammock support ropes in my backyard. The attached photo was taken June 17 at 3 p.m. in the Silver Lake neighborhood of Los Angeles (about four miles northwest of downtown). The size and height of its cephalothorax in proportion to its abdomen is what I found most interesting. In terms of scale I’d guesstimate the creature in its ”hunkered down” position as shown to be not more than a single centimeter in length. I wasn’t able to photograph it in motion. I’m a huge fan ow What’s That Bug. Thank you for any solution you can be to this mystery spider.

Possibly Lynx Spider

Dear Will,
Sadly, we have not had any luck trying to identify your spider either.  We have a vague recollection of seeing images of similar spiders, but we are drawing a blank.  We tried looking through images on BugGuide, but alas, no luck.  Hopefully our readership will be able to provide some assistance in this identification.  A view of the eyes from straight on might help.  Did it have a web nearby?

Update
Hi Daniel,
Thanks so much for the response. Part of me is glad I at least didn’t submit “The Most Common Spider In The Universe.” I found it in the same spot as it had been yesterday and have attached a couple images snapped in hopes they might help; one more straight-on and another of what might be its web/lair.
Best,
Will

Possibly Lynx Spider

Hi again Will,
Thanks for the additional documentation.  We hope we will eventually be able to provide an ID.  You may want to provide a comment to the posting to ensure that in the future you will be notified of any activity or comments.

A comment from a reader directed us to the genus
Hamataliwa on Bugguide which appears to be correct.

This will be the last time I visit your site. You have sent me two pass words and neither work. Just wanted to tell you that your life span information on the Green Lynx spider is incorrect. I have watched one continuously and she is now sitting on her second egg sac. She survived the December rains with her first spiderlings and became pregnant again. Since spiderlings winter over, I have to assume she started life in 2009. You can see the older egg sack in the picture to the left

Green Lynx Spider with Egg Sac

Dear Meredith,
We are sorry to hear that you are having technical difficulties.  Our technical staff is completely separate from our editorial staff.  All we can say is that if our awesome webmaster cannot correct your problem, there must be a major system incompatibility that is creating the problem.  Thanks for sending your photo of a Green Lynx Spider protecting her second egg sac.  Green Lynx Spiders may produce multiple broods, but even under ideal conditions, it would be highly unusual for a female to live through a second season.

I was happy to spot these tiny spiders yesterday morning.

Green Lynx Spiderlings

Hi Barbara,
Thanks so much for continuing to document to the life cycle of the Green Lynx Spider in your garden.  Your hatchling Spiderlings are so cute.  The weakest among them will most likely provide food for their more aggressive siblings, ensuring that only the most robust individuals with the best survival skills will contribute to the gene pool of future generations.  Since we both know that Daniel is the only person who deals with the content of What’s That Bug? I can dispense with the use of the royal we in this response.  I am currently creating some homemade signage to post in Elyria Canyon Park where there is a patch of native milkweed,
Asclepias eriocarpa, that comes up every year, though it sometimes gets trampled to the ground when brush clearance is too aggressive along the paths.  I would like permission to use some of your monarch caterpillar photos with the signage, though I have never seem any Monarch Caterpillars at the location.  More on this later because I will be late for work if I don’t tear myself away from the computer now.

Green Lynx shelters Egg Sac

Dear Barbara,
Thanks for continuing to send us documentation the female Green Lynx Spider living in your garden.  We have stated previously that the strong maternal behavior exhibited by this species is rivaled by few other species of spiders, though the Nursery Web Spiders are named because of their protective instincts.  Since our Mt Washington offices are but a few miles from South Pasadena, we know that this protective Green Lynx has already kept at least five inches of precipitation from drenching her eggs during this Pineapple Express storm that is predicted to be the worst in a decade by the time the rains subside on Thursday.

Update: December 30, 2010
Hi Daniel.  I’m sad to report that the Green Lynx Spider did not survive.  Too much rain and nothing to eat I suppose.  The egg sac looks collapsed as well.  I haven’t taken pictures, because it’s just too sad, but I have left it on the roses, hoping the baby spiders will emerge in some kind of Charlotte’s Web happy ending.

Hi Barbara,
Green Lynx Spiders only live a single season, so this death is not unusual.  We hope you see some young spiderlings in the spring.

I was very happy to spot this lynx spider mother. I’ll keep on eye on her and try to get some baby spider pictures.

Green Lynx with Egg Sac

Dear Barbara,
We are happy that you have located your female Green Lynx Spider and that she has produced an Egg Sac.  She will defend it against any potential predator, and the seemingly fearless mother does not even seem intimidated by a human thousands of times her size approaching her precious clutch.  Luckily, Green Lynx Spiders are not harmful to humans.
